Order a custom dataset & annotation
When the data you need doesn't exist yet, order it. The Custom Dataset section is the data labeling and annotation side of Dataset Finder: instead of searching for an existing dataset, you have one built to your exact specification by expert human annotators.
This covers the full range of annotation work — bounding boxes, polygons, segmentation masks, keypoints, entity spans, classification, transcription, and ranking or preference data — across computer vision, NLP, document processing, Gen-AI, content moderation, and medical data. You can also request a dedicated annotation platform for your project if you need one.
Open Custom Dataset from the left menu, then select New Request to start. Your existing orders live under My Datasets Orders in the same place.
Two ways it works
A custom request can go one of two ways:
We source it for you
In some cases we can find or assemble the data you need on your behalf, then label it to your spec.
You bring the raw data
Most often, you upload your raw data plus your annotation guidelines, and our team labels it exactly as you instruct.
What happens after you submit
- Credits are deducted when you submit, based on the complexity and volume of what you ordered. You're told if you don't have enough credits before you submit.
- You get a delivery date. Even the largest requests are typically delivered within a month.
- For very large or ambitious requests, we'll reach out to set up an Enterprise contract instead, so we can optimise the effort, your costs, and the delivery timeline together.
